Cantilever seismic calculation of mode-superposition response spectrum method for the gravity dam of Gutianxi first cascade;

Considering the seismic dynamic water pressure and foundation elasticity,the dynamic response of Baoquan masonry gravity dam is calculated by using the three-dimensional finite element method and the mode-superposition response spectrum method given in Specifications for Seismic Design of Hydraulic Structures(DL5073-2000).

By using the finite element ANSYS,the paper calculates the whole structure,and analyzes its response under the earthquake action by using the mode-superposition response spectrum method,obtains the natural vibration characteristics of the structure and its different characteristics under the vertical and horizontal earthquake action through the analysis.

A design process and the design method for viscoelastic dampers(VEDS) were in troduced on the basis of response spectrum method.

Based on viscous-spring artifical boundaries,seismic response analysis of the Bell Tower are conducted using mode decomposition response spectrum method.

The simplified method to calculate vertical earthquake response recommended in code is unable to calculate the secondary resonance and the vertical shearing response,but the modal analysis method by response spectrum can accurately calculate these effect.

The response spectrum analysis of the terminal building of Beijing Capital Airport under multi-dimensional earthquake input;

Full bridge earthquake response spectrum analysis of Tianjin Liulin Bridge;

The earthquake force is calculated by response spectrum analysis method through the finite element program which is midas in order to bring forward basis to the quake-proof design of big span concrete continuous beam pier shaft and foundation section.
